To all whom it meg concern: 7

Be it known that I, ALEXANDER RIsrEL, a citizen ofthe United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful. Door Check and Holder, of which thefollowingis a specification. p H r The present invention relatesto improve mentsin door checks. and holders, the present invention being an improvementupon the door check andholder set forth in my Patent No. 1,053,222granted February 18, 1913, one object of the present invention being theprovision of a lug carrying means for properly gripping the upper end ofthe casing to position the lug properly to be abutted by the resilientabutment of the door connecting arm and to hold and prevent theaccidental closing of the doorafter once positioned.

With the foregoing and other objects in view which will appear as thedescription proceeds, the inventionresides in the combi nation andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of whatis claimed Without departing from the spirit ofthe'invention.

In the drawingsFigure 1 is a front elevation of the complete door checkand holder with the jointed ,arm I removed. Fig. 2 is a top plan view ofthe complete door check and holder. Fig. 3 is a section taken on line3-3 of Fig. 2. Fig. 4 is a section taken on line 4-4 of-Figp3. Fig. 5 isa section taken on, line 55 of Fig.3. Figs. 6 and 7 are detailvie'wsof aportion ofone,

of the jointed arms carrying the anti-frictional abutment for engagingthe cover lock. Figs. 8 and 9 are detail fragmentary perspective viewsof cooperating portions of the clamping band and actuating means forgripping the open end of the casing to hold the cover securely in place.

Referringto the drawings, the numeral 1 designates the casing of thedoor check and holder, which is provided internally and intermediate ofits ends with the interior screw threads 2 for the reception offthepartitioning disk 3. The spindle '6 projects through the disk 3 and iskeyed to the exteriorly screw threaded member 9 mount ed for movement inthe spiral groove 11 of v Application filed December 5,1913. lSerial No.804,922.

Specification ofLetters-Patent. atent O 3, 1914 the plunger 12. i Avertical slot 21 is formed in the'circumferential wall of the plunger 12and engages or fits'upon the pin 22'carried 1n the casing 1, thuslocking the plunger 12 against rotation so that" as the stem 6 1soscillated, the member 9 will impart a vertical'sliding movement totheplunger 12,

the spring 21 acting as a cushioning means for the ,plunger'in itsdescent and also assisting-in the ascent of the same.

The I spring-26 is connected to operate the stem, 6 throughzthe sleeve29 which is disposed for oscillation within the central openmg 30 of thedisk cover 31, said cover 31 being providedwith the rim orfiange 31which fits snugly within the upper end of the casing 1 and thus sealsthesame. this means, thesleeve 29 may be independent of the. spindle 6, andalso the cover 31. Formed integral with the sleeve 29 is a disk32Wl110l'1 is adapted to fit above the; cover 31. the same beingprovided with. plurality of recesses 33 inits periphery. The

reduced end 6':'.Qf the spindle 6 has detachably connected thereto bymeans of the split clamping end 34, the inner arm 35. A lug 36 is formedintegral with the arm 35 and h as pivoted-i therein, a pawl 37, whichisnormally heldby its spring 37 in engagement .with the periphery of thedisk 32 so as to, when "thejarm35 is'moved in the directionfof the arrowFig. 2, rotate the disk 32 and thus place the spring 26 under tension. H

lug 38 isformed integral with. and projects from the periphery of thesplit clamping band 46 at one point thereof, and is disposedto cooperatewith the abutment 39, which in the present instance carries theanti-frictional roller a so that when the arm 35 is moved to a positionto hold the door open, theroller will bepositioned upon the oppositeside of such lug 38 to that shown in Fig. 2, and the arm'will thus be,locked against movement. The pin 39 is carried by a block 41 disposedfor sliding movement within the casing 42 formed in the arm 35 andcovered by the plate 40. A spring 43 is disposed therein to normallyhold the block 41 and the roller a toward the periphery of the cover 31.1 By, this means, when the roller a is forced in engagement with the lug38 the same will roll thereabout and thus depress the spring 43 astheblock 41. is moved outwardly, said spring snapping the same in behindthe lug 38 and thus looking the parts in the desired position with thedoor open.

The adjustable arm 4% is as usual pivoted to the outer end of the arm35.

A head or rim e5 forms a limiting means for the clamping band 4:6, thatcarries the lug 38, and said band has formed integral therewith, the twoears 47, recessed upon their outer faces as at 48. are apertured for thereception of the clamping bolt 50, which binds the two arms or links 51,relatively to the ears 41-7, the arms 51 being provided with the roundedprojections 52 for registrationwith the recesses 4L8, and so that whensaid arms are pulled downwardly through the instrumen tality of the bolt53, the link 54, and the adjusting member 56, the ears e7 are forcedmore closely together and the band 46 is clamped more firmly upon thecasing. The member 56 is provided with the projection 55 to which thelink 5%is secured, and has its socket 57 embracing the cylindrical boss58 carried by the casing. A screw 59, having its head 60 accessible ismounted in the member 56 and limits the upward movement of the member 56relatively to the boss 58. A spring 61 is provided and has itsterminals, which normally separate, connected to the ears 4:7 to assistin opening the band 46.

The lower end of the member 56, is in the form of a knob to permit theeasy movement downwardly of such member to more rmly clamp the band 46,after the door check and holder has been' installed, the screw 59, beingthus adjustable with a screw driver to hold the member 56 in suchdesired position.

What is claimed is: i

l. A door check and holder, having a supporting casing, a split clampingband surrounding the upper end of said casing, adjustable means pivotedto the band and connectedto the lower end of the casing for These earsl7 7 regulating the tension of the clamping band, a fluid cushioned andspring actuated means mounted in and exteriorly of the supportingcasing, a folding arm connected to the latter means, and cooperablelocking means for the folding arm carried by the band and the foldingarm. v V

2. A door check and holder, having a supporting casing, a springactuated folding arm journaled in the supporting casing, a clamping bandsurrounding the upper end of the supporting casing, manually operatedmeans for adjusting the band and looking it in clamped position, an armholding lug carried by the band, a resiliently mounted abutment carriedby the folding arm for coaction with the lug of the band to lock the armagainst the tension of its spring, said manually operated meansincluding a cam mechanism operably connected to the clamping band, aslidable operating member connected thereto and to the supportingcasing, and means'for locking said operating member in clampingposition.

3. A door check and holder, having a main supporting casing providedwith a stud at one end, a folding arm mounted upon the supporting casingfor swinging movements, a spring for opposing the move ment of the armin one direction, a clamping band surroundingthe supporting casing,cotiperative means carried by the band and arm for limiting the movementof the arm in one direction, a pivoted wedging member, connected to theband, and an adj usting and operating member for the wedgingmembermounted upon the stud of the supporting casing.

In testimony that I claim the foregoing as myown, I have hereto afiixedmy signature in the presence of two witnesses.

I ALEXANDER RISPEL.
